The area of the sector that has a central angle of 120 degrees and radius of 8 units is 64π / 3 units²
<h3>Area of a sector</h3>
The area of a sector is defined as follows:
area = ∅ / 360 × πr²
where
- r = radius
- ∅ = central angle
Therefore,
r = 8
∅ = 120°
Hence,
area of the sector = 120 / 360 × π × 8²
area of the sector = 1 / 3 × π × 64
area of the sector = 64π / 3 units²

Answer:
7892 dolphins
Step-by-step explanation:
let P denote the dolphin population.
-Notice this is an exponential decay and is denoted as:
Where;
- is the population at time t
- t is the time
- r is the rate of decay or decrease in population
- is the initial population size.
#Given t=30yrs, =20000 and r=3.1%, the population after 30 years is estimated as:
Hence, the dolphin population after 30yrs is approximately 7892
slope is determined by your rise over your run or the equation (y2-y2)/(x2-x1)
putting in the given points gives you (43-60)/(-60-42)
this gives you -17/-102 negative divided by negative give you a positive.
both divide by 17 giving you a slope of 1/6
